RUTELIN.E 85 







Prothorax distinctly less than twice as wide as long in both sexes, the 

 sides converging almost evenly from base to apex and feebly, sub- 

 evenly arcuate, except in subenodis 2 



Prothorax much shorter, more than twice as wide as long in both sexes, 

 the sides becoming gradually more parallel in about basal half. . .5 



2 Body larger in size than Plusigtis gloriosa, polished, the head and 

 pronotum more obscure, piceous-green, the elytra brighter though 

 rather dark green; under surface, legs and pygidium dark testaceous, 

 with more or less green lustre, nearly wanting on the legs, the meta- 

 sternum more bluish; head barely more than a third as wide as the 

 prothorax, the eyes separated by less than four times their width, 

 the surface behind a line through the middle of the eyes extremely 

 minutely and remotely punctulate, before that line and throughout 

 the clypeus coarsely, deeply and confluently punctate, the clypeus 

 trapezoidal, with arcuate sides and arcuato-truncate reflexed apex, 

 twice as wide as long, nearly flat, the suture obsolete only medially; 

 antennaa testaceous, the club much shorter than the stem; prothorax 

 convex, shallowly sinuate at apex, which is but little more than half 

 as wide as the base, the basal lobe distinct; basal angles broadly, 

 the apical more narrowly, rounded; marginal bead thin, much ele- 

 vated apically ; surface very finely and remotely punctate throughout; 

 scutellum wider than long, ogival, obscure subcupreous and finely 

 sparsely punctate, well developed in size and notably larger than in 

 the other species; elytra oblong, a fourth longer than wide, nearly a 

 fourth wider than the prothorax, parallel, with broadly arcuate sides, 

 rapidly obtusely rounded at apex, the striae of deep punctures deeply 

 impressed internally and externally, but more feebly between the 

 humeral and apical umbones; second interval with some coarse 

 scattered punctures; pygidium sericeous, with rather fine irregular, 

 transversely interlacing lines, which are not at all dense, the surface 

 smooth and finely, remotely punctured toward tip; metasternum 

 punctured throughout, sparsely mediad. Length (9) 26.0 mm.; 

 width 14.0 mm. Mexico (Colonia Garcia, Sierra Madre Mts., 

 Chihuahua), Townsend *aeruginis n. sp. 



Body much smaller in size than in Plusiotis gloriosa, polished as in the 

 preceding and all the other species; scutellum smaller 3 



3 Last joint of the maxillary palpi (cf ) with a large deep excavation 

 almost throughout its length. Form oblong-oval, moderately con- 

 vex, verdigris-green throughout above, testaceous beneath, the 

 sterna pale blue, the abdomen and legs with strong cupreo-aeneous 

 lustre, the pygidium bright shining green, paler than the elytra; 

 head very small, the eyes separated by three and one-half times their 

 width, feebly convex, more or less finely, sparsely punctate through- 

 out, the clypeus more strongly and closely, unusually short, much 

 more than twice as wide as long, rounded, the apex distinctly reflexed; 

 antennal club almost as long as the stem; prothorax narrowing more 

 rapidly anteriorly than posteriorly, the sides almost parallel in 

 basal three-fifths, the base broadly and strongly lobed, all the angles 

 distinctly defined, not more than blunt; surface everywhere minutely, 

 remotely punctate; scutellum smooth, irregularly punctured near the
